Rational Numbers(Q)
are numbers which can be expressed as a quotient (fraction).
A rational number is a part of a whole number and is shown as an integer numerator and a non-zero integer denominator.
These quotients can also be written as decimals, percentages or negative exponents.
When rational numbers are expressed as decimals, they can be terminating decimals (0.3) or non-terminating decimals (0.3333333....).
